Specification of Letters Patent.

Patented Nov. 1915.

Application fi1ed February 10, 1913. Serial No. 747,491.

To aZZ whom it may concern:

Be it known that we, ALoNzo T. ADAMs and JosErH DAIN, citizens of theUnited States, residing at Moline,'in the county of Rock Island andState of Illinois, have invented certain new and useful Improvements inGrain-Elevators, of which the following is a specification, referencebeing had therein to the accompanying drawing.

' Cur invention relates to that class of mechanical structurescomprising portable wagon-clumps and elevators employed toremove a loadfrom a wagon and deposit it in some other receptacle, and it consists ofa novel and economical arrangement and operation of the various parts aswill be more clearly described and claimed hereinafter.

Referring to the drawings in which similar numerals indicate identicalpartsFigure 1 is a perspective view. Fig. 2 is a plan of the receiverand part of the elevator. Fig. 3 is a side elevation of Fig. 2, and Fig.4 is a detail section.

In a structure of this description, power is conveyed to the dumping andelevating mechanism through a power-shaft 1, any suitable power beingemployed. The dumping apparatus is of an ordinary type, consisting of aframe 2, from which is suspended a vertically movable bar 3 havingsuspended therefromloops 4 adapted to engage with the front end of awagonto raise it so that the load will be deposited in a receiver 5 atthe foot of an elevator 6, and forming part thereof. The bar 3 is raisedor lowered by means of a cable 7 on a drum 8, the latter operated fromthe power-shaftl by means of intervening gearing in a manner well knownin the art.

The receiver 5 is located so that anywagon being dumped will depositthe'load therein, the latter falling upon a conveyer 9, atthe bottom ofthe receiver5, moving toward the elevator 6 and carrying thereto thematerial received from the wagon. The con veyer 9 consists of sprocketchains 10 and 11 engaging with sprockets 12, and having secured to themat suitable intervals blades 14. The sprockets 12 are idlers and revolveon a shaft having bearings in the outer end which engages with asprocket 20 secured on a tubular shaft 21 and receiving motion from thepower-shaft 1 as will be explained. The tubular shaft 21 revolves inroller bearings 22 and 23 forming part of brackets 24 and 25 secured tothe sides of the elevator box 26. V

The power-shaft 1 is preferably composed of three sections, a, Z), andc, the central section I) is journaled in the tubular shaft 21, and hasupon one end a member 27 of a clutch which is, free to movelongitudinally I to which is pivoted a vertical lever 32 which engageswith the ring 30, so that a movement of the lever 32 toward the receiver5 will engage the clutch member 27 with a clutch member 33 on the faceof the sprocket 20 to operate the conveyer 10 in the receiver 5 throughthe chain 19 and sprocket 18, and

at the same time imparting motion to the conveyer-M in the box 26forming the elevator, the'latter conveyer being similar in constructionto the conveyer 9, and carried on sprockets 35 and 36 secured to thetubular shaft 21 and revolving therewith.

The power-shaft section 0 is coupled to a clutch member 37' which isloosely mounted on the power-shaft section b, and power to operate thedumping mechanism through the section a is conveyed to the latter bymoving the lever 32 away from the receiver 5-until the clutch members 27and 37 are in engagement. Normally the clutch member 27 is out ofengagement withthe members 33 and 37 as shown in Fig.4, so that theconveying and elevating mechanism can be operated independently of thedumping mechanism, or both may remain idle while the sections a and b ofthe power-shaft 1 are revolving.

On each side of the receiver 5 is hinged a door 38 and 39 and adapted tofall into the position shown in dotted lines in Fig. 4 forming a hopperwhen the load from a wagon is dumped into the receiver, the limit 1 ofthe door movement being regulated by suitable hook arms attached theretoand adapted to catch on the receiver in a well known manner.

To automatically start the operation of the conveying mechanism a rod 40is rockable in bearings'on a side of the receiver 5, one end ll of saidrod being bent, as shown in Fig. 3, to present a greater bearing surfaceagainst the door 38; theother end of the rod &0 is bent outwardly andupwardly forming a crank arm 42 in which is a vertical slot 43 connectedtothe crank-pin 42 in the slot 43 is a rod 44: whichprojects through thetubular shaft 15 and is attached to the lever 32; a coiled spring 45 onthe rod 4%, and interposed between the lever 32 and sprocket 18, tendsto keep the door 38 in a closed position; it will be readily apparentthat the pressure of the material dumped into the receiver will causethe door 38 to drop, rocking the rod 40 and actuating the rod 44 to movethe lever 8:2 toward the receiver 5 and engaging the clutch members 27and 33 so'that revolution of the powershaft sections a; and b willimpart motion to the conveying and elevating mechanism; when thepressure on the door 38 is'removed the expansion of the spring 45 willclose said door by rocking the rod 40 to its normal position, and at thesame time the clutch members 27 and33 will be disengaged and theconveying and elevating mechanism will stop.

What we claim is 1. The combination with an elevator, of power actuatedmeans for operating said elevator but normally out of engagementtherewith, a lever adapted to be manually operated to connect theelevator with the power actuating means, and means to auto maticallyoperate said lever to connect the elevator with the power actuatingmeans.

2. The combination with an elevator, of power actuated means foroperating said elevator but normally. out of engagement therewith, areceiver forming part of the elevator-and having a door thereon adaptedto swing outwardly, and means operated by the outward swing of said doorto connect said elevator with said power actuating means.

3. The combination with an elevator, of power actuated means foroperating said elevator but normally out of engagement therewith, areceiver forming part of the elevator and having a door thereon adaptedto swing outwardly, a lever operable to 0011- nect the elevator with thepower actuating means, and a rod engaging with said door and connectedto said lever to actuate the latter by the downward swing of the door toconnect said elevator with the power actuating means. v

4. The combination with an elevator, of power actuated means foroperating said elevator but normally out of engagement therewith, areceiver forming part of said elevator and having a door thereon adaptedto swing outwardly, a lever operable to connect the elevator with thepower actuating means, a rod engaging with said door and extending alongthe receiver to which it is rock-ably secured, a crank-arm on said rod,a rod extending transversely of said receiver and connected to saidcrank-arm and said lever to actuate the latter by the downward swing ofthe door to connect the elevator with the power actuating means.

5. The combination with an elevator, of power actuated means to operatesaid elevator, comprising a tubular shaft, means connecting said shaftwith the elevator, a shaft within the tubular shaft and connected with asource of power, and means automatically operable to connect said shaftsfor simultaneous movement.

6. The combination with an elevator, of power actuated means to operatesaid elevator, comprising a tubular shaft connected with the elevator, ashaft within the tubular shaft and connected with a source of power,means manually operable to connect said shafts for simultaneousmovement, and means to automatically actuate said manually operablemeans. v

In testimony whereof we affix our signatures, in presence of twowitnesses.
